Centre of Gravity Apparatus STEM Lab Manufacturer,Supplier and Exporter in India
Product Code : SCL-MH-12512
Quick Answer: The Centre of Gravity Apparatus locates the centre of gravity of flat shapes by the plumb line method. Laminae hang from a knurled suspension pin on a stand, and lines traced from two suspension points cross at the centre of gravity.

About This Product
A shape is hung from one hole with the plumb line on the same pin, and once both are still a line is drawn along the cord. Repeating from a second hole gives another line, and where the two cross is the centre of gravity. Balancing the shape on a pencil point at that spot confirms the result and leads into stability in buildings, aircraft and vehicles.
Frequently Asked Questions
How does the Centre of Gravity Apparatus find the centre of gravity?
Hang the lamina from two different edge holes in turn and trace the plumb line each time. The point where the two lines cross is the centre of gravity.
Is the centre of gravity the same as the centroid for these shapes?
For uniform shapes like those in the kit, yes. The centroid is the geometric centre; the centre of gravity is where the weight acts, and they coincide when the material is uniform.
